Evaporative cooling is one of the oldest and simplest methods for cooling air. Our well-designed industrial and commercial quality evaporative cooler can reduce the buildings total energy consumption by even more than what is mandated by “Title 24” of California Energy Efficiency standard.

Westaire's high performance Cel-pack Evaporative Cooler incorporates an adiabatic process, which relies on water evaporation with extremely low energy consumption to produce a high volume of cooling. Westaire's Direct Evaporative cooler provides a 90% efficiency rate. It is a self-contained unit incorporating CEL-dek or GLASdek media, which are constructed from special cellulose paper, that is saturated with insoluble anti-rot salts and rigidifying saturates. The unique cross-fluted self-cleaning design of these pads introduces a highly turbulent mix of air and water for optimum heat and moisture transfer.

The standard capacities range from 4,000 to 42,000 CFM. Special units are built up to 130,000 CFM.


The surface of the pads are designed for minimum 500 FPM face velocity. This eliminates the need for arrestors or eliminator sections. Components utilized in Westaire’s Cel-pack Evaporative coolers conform to the requirements and standards of recognized technical and industrial organizations such as; ASME, UL and AMCA.


GLASdek with TUFedg:

Is made from a flame retardent material fortified with special rigidifying agents. The cross fluted, unequal angle pad design induces a highly turbulent mix of air and water for optimum heat and moister transfer. this unique design also functions to continously direct more water to the air entering face of the pad, where the most intense evaporation occurs. UL certified and fire rated UL-900 Class 2


CELdek Media:

A high efficency evaporative cooling media that is engineered to provide maxiumum cooling and humidifcation, low pressure drop and years or reliable service. Media is designed with a self cleaning flute design, specially treated with algae resistant substrate. Maintance can be done while system is in operation.
